This function is used to split a selected surface into two surfaces using a specified line. The dialog box is illustrated in Figure 5.2.20.
● SELECT SURFACE
Click this button to display Select Surface dialog box to select multiple surfaces.
● SPLIT BY
There are eight methods for the user to split the surface.
Figure 5.2.20 Split Surface
1. SELECTED LINE
The user may select an existing curve in database as split line.
2. NEW LINE
The user may select up to 500 locations on the surface to define a polygon as the split line.
3. NEW SPLINE
The user may select up to 500 locations on the surface to define a spline line as the split line.
4. TWO BOUNDARY POINTS
eta/DYNAFORM splits the selected surface once two points are selected on the boundary.
5. SECTION U-V LINE
The user can select a U-V line on the selected surface using mouse cursor. The surface will split along the U-V line.
6. SURFACE INTERSECTION
Once two surfaces are selected, the first surface is split at the intersection line with the second surface.
7. OVERLAP SURFACE
This function allows the user to split a selected surface using an overlapping surface that is smaller than the selected surface. The first selected surface will split along the boundary of second surface.
8. UV Plane of LCS
This function allows the user to define an LCS and the surface is split at the intersection line with U-V plane in LCS.
● Define Project Direction
1. Z-Axis
2. View Direction
3. Surface Normal: default option
4. User Define: refer to Section 5.1.4.
● Tol: Define the tolerance of trim line and the boundary after trimming along the projection direction.
